Research Title: Coupling Optional Polya Trees and the Two Sample Problem

Research Description: Epistasis is speculated to play important roles in the epidemiology of common diseases. Current methods of testing interactions have achieved limited success and are ineffective in the presence of genetic heterogeneity—when people clinically have the same disease for different genetic reasons. Li’s research focused on developing statistical and computational methods for testing interactions that are robust to genetic heterogeneity. He used large scale computation to seek genetic patterns that account for a small proportion of the patients.


Li is a professor of statistical science at Duke University.
